    I have just bought the following router: Wireless-G 125* High-Speed Broadband Router and Access Point (http://www.buffalo-technology.com/p...igh-speed-broadband-router-and-access-point/).

    We have virgin media internet at home (http://allyours.virginmedia.com/websales/service.do?id=2).

    Basically, they gave us a cable modem (with a coaxial cable connection).

    We had to install some software on a windows XP PC, and authorise it, and then we were able to access the internet using a RJ-45 cable. I connected it to my PC (Ubuntu 7.04) and it was working without a problem.

    Since there are a lot of people in our house we bought the wireless router to share the internet.

    The problem right now is that after I connect it to the wireless router (i.e. the cable modem to the WAN port of the router) I can connect to the router but cannot access the internet.

    I managed to set up a WEP key for my router (by going to:, username: root, pw: [blank]).

    There were a lot of other settings but I'm not really sure what to do, or how I should go about allowing internet access for my router.

    I am generally familiar with ubuntu, but unfortunately I don't know enough about the networking tools. Also, its strange but now if we connect the modem directly to the windows PC I get limited or no connectivity (but that could be a separate problem). Right now I want to try and get the settings for the router.

    To summarise:

    - The cable modem is connected to the Buffalo router with a RJ-45 over the WAN port. I can connect to the router, but can't access the internet. There are some settings, such as default gateways, dns servers, and mac addresses, but my problem is two-fold. I don't know what information I need to put in, and also i don't know where to find the information in ubuntu (i.e doing ipconfig/all in windows).
